Well, where do we even begin? There's now an official petition aimed specifically at encouraging Microsoft to bring Halo 3 to the PC. After it was spotted in the Steam registry there was much rejoicing. Sadly, for Halo fans, this was quickly and firmly rebutted by Microsoft in no uncertain terms. But when it was also spotted in updates for AMD drivers there was much rejoicing. Until that, too, was refuted. So the fans decided, enough is enough, and started a petition which you can find here, that already has over 2000 signatures. How much, if any, difference it will make remains to be seen. But the success of the Dark Souls petition last year is inspiring.
